In a fluid, the following forces are present
Gravity force (Fg) due to gravity
Pressure force Fp due to pressure of fluid
Viscous force Fν due to viscosity
Tension force Fs due to surface tension
Turbulent force Ft due to turbulence.
Fc due to compressibility.
∴ Fnet = Fg + Fp + Fν + Fs + Ft + Fc
- If Fnet = Fg + Fp + Fν + Ft this is known as Reynold’s equations of motion.
- If Fnet = Fg + Fp + Fν this is known as Navier-Stokes equation of motion.
- If Fnet = Fg + Fp this is known as Euler’s equation of motion.
